For decades, scientists have dreamed of computer chips that manipulate light rather than electricity. [...] For now, though, optical computing remains a dream.
Enter a beetle known as Lamprocyphus augustus. In a study published this week in Physical Review E, researchers at the University of Utah describe how the inch-long Brazilian beetle's iridescent green scales are composed of chitin arranged by evolution in precisely the molecular configuration that has confounded the would-be fabricators of optical computers. [...]
"Optical computers could do in a second what now takes days or weeks," said Bartl. "And we're providing the materials."Full story at Wired.com
